GAS BURNER.

Application fl1ed Ju1y 24, 1924. Serial No. 727,879.

To all whom it may concern.- i Be it known that BERRY A. BAXTER, acitizen of the United States of America,residing at Mansfield, in thecounty of Richland and State of Ohio, has invented certain new anduseful Improvements in Gas Burners, of which the following is aspecification.

This invention relates to gas burners.

It is well known to those skilled in the art that in the use andoperation of gas heaters especially of the radiant type, that moreperfect combustion can be had if means are provided for so mounting andsupporting the'radiants that free circulation of air will be permittedaround the burner between the. bottom of the radiants and the top of theburner tips.

The primary object, therefore, of the present invention is to providemeans for mounting and supporting the radiants of the heater in such amanner as to permit free circulation of air around the burner betweenthe top of the burner tips and the bottom of the radiant and also toprovide means for retaining the bottom of the radiants in alignment andin a central position relative to the burner jets.

A further object is to provide a burner and so apportion the jets of theburner tips that the pressure of the gas will be equalized so that theflame of the burner will project up to the same height and to burnwithin and around the radiants uniformly from the jets in the tips.

Another object of the present invention is to provide means to choke orrestrict the lower passage through which the air and gas mixture passesforming a neck-like portion or the like to confine and restrict themixture therethrough, whereby the mixture of gas and air are brought andmerged together to make more perfect mixture, thereby providing meansfor better combustion of the mixture.

A further object is to provide means whereby the burner tips can beinserted in suitable apertures in the burner and held properlypositioned therein through the medium of tongue-like flanges with theaid of one screw which serves to securely fasten two burner tipssecurely to the top of the burner.

A further object is to provide means of constructing a burner of sheetmetal whereby the cost of construction in labor and material is reducedand providing a smooth and unobstructed interior and exterior therebyreducing the friction of the flow of the; mixture through the passagesof the burner and also providing a burner with a smooth and unobstructedsurface for enamelin' or the like for finishing purposes.

ith these and other objects in view the lnvention resides in thefeatures of construction described and the principle on which theyoperate, arrangement of parts and combination thereof, which willherelnafter be fully described. A structure which is the preferredembodiment of this mvention is clearly illustrated in the accompanyingdrawing forming part of this specification, in which: 1

Figure 1 is a side view of the burner of the burner which is preferablymade of,

sheet metal and of hollow construction to provide passage-ways for theflow of air and gas to the burner tips 3, which arepreferably-providedwith openings or jets 4. The lower part of the burner1 is pressed or crimped inwardly to form a restricted or small passagefor the gas and air at the point indicated at 5. The end of the lowerportion 6 is provided with a mouth to provide for full and freeadmission of air so as to permit it to thoroughly mix with the fuelsupplied from the source of supply as indicated at 8.

A partition member or plate 9 is interposed between the burner parts 1and 2 thereby forming separate and distinct passage-ways for the fueland air between the upper and lower parts 1 and 2. The partition plateis inwardly ressed or crimped as indicate at 6 toward t e int indicatedat 5 of the lower portion 1 t ereby restricting the passage-way formedby the lower part 1 of the burner and choking (or restrictmg) the freeflow of fuel and air and at this point forming a neck-like passage-Waybetween the plate 9 and the lower part 1.

It will be noted that at the points 5 and secure the upper and ower 6the plate 9 is provided with sides 10 and 11, whiclrwith the bottom 12of the plate forms a trough-like ortion. In order to rtions 1 and 2 ofthe burner together and iaving the plate 9 interposed therebetwen,without the use of the rivets or screws, fastening means are madeintegral with the top and low pertions 1 and 2, as follows:

The edges of the part 2 have loops 13 and 14 formed thereon with theopenings extending in opposed relation toward the interior of ,theportion 2. The portion 1 has outwardly extending flanges 15 and 16fitted within the loops 13 and 14 and the plate 9 is also provided withoutwardly extending flanges 17 and 18 WlllCh are fitted within the loops13 and 14. The loops 13 and 14 are then beaded or pressed togetherholding the bottom portion securely connected to the upper portion 2with the plate 9 interposed therebetween, thereby providing a burnerwith an upper and lower passage-way for the mixture of air and gas.

The u per portion of the burner 2 is also provide with a series ofapertures 19 which are preferably formed rectangular in shape; Eachburner tip 3 is provided with a flange as shown at 20 and it is adaptedto be fitted to the aperture 19 formed in the top portion 2 of theburner. Preferably at each corner of the burner tip supporting members21, 22, 23, and 24 are formed integral with the burner tip andpreferably extend up on a plane or above the top of the jets 4 of theburner as indi-.

cated at 25. Extending vertically therefrom lugs 26 are provided andpreferably made integral with, the supporting mem- The lugs 26. areadapted to fit within the bottom of the radiants 27 to position, retainand maintain the radiants in a central position over the jets as stated.The supporting members support the radiants in such a manner as topermit of free circulation of air around the radiants and jets betweenthe bottom of the radiants and the top of the jets. As the top of thejets. of the burner tip are rounded as shown in Fig. 5 at 28 and 29 aircan circulate freely around the burner jets and bottom of the radiantseven though the bottom of the radiants are slightly below and on a planewith the top of the jets.

Attention is called to the fact that the fuel mixed with air passesthrough the passage-way inthe lower portion 1 of the burner in the firstinstance and then passes up and into the passage-way of thepart 2flowing into the passage-way at the flush ends of the body portions ofthe burner 2 with more velocity or pressure near the cap 30, thereforethe flames emitting from tneburner tips burn stronger and the flamestical direction than at the ends of the burner portions near the plate31. In order,

therefore, to re ulate the flow of the mixture so that 1t will be moreuniform throughout the series of burner tips and to counteract thepressure at the flush end of the burner, the jets 4 are made less innumber or smaller in size or area in the first two burner tips adjacentto the flush ends of the burner portions covered by the cap 30. In otherwords as shown in Fig. 1 there are five (5) jets formed in the firstburner tip, six (6) in the second tip and seven (7) 1n the remainingtips. The .construction of the tips, as described, has the effect ofretarding or stopping more or less of the quantity of mixture that wouldordinarily pass through the conventional jets on account of thedecreased size of the jet openings, or of the decreased number of jetsformed in the tips adjacent to the end where the pressure is greatestand allowing an equal quantity of mixture to pass through theconventional jets of the other tips, where the pressure is not so reat.

The cap 30 is fastened to one on of the lower parts 1 and 2 of theburner and the plate 31 is fastened to one end of the upper part 2 ofthe burner by a through-going bolt 32 and a nut 33.

From the above description it will be noted that the body of the burneris composed of but three (3) parts, a lower portion, an upper portionand an intermediate partition plate, which is interposed between theupper and lower portions. It will also be noted that all of these partsare held in their assembled position through the medium of flanges bythe beading method, which requires no rivets, bolts, screws, welding orthe like.

It will also be noted that a neck-like portion is formed. in the lowerpart Lof the burner at a predetermined point in the passage-way to forcethe gas and air to mix and merge more thoroughly together on account ofthe confined passage-way, and then allowing the gas and air to spreadmore or less and flow into the upper passage-way formed in the part 2 ofthe burner, to the burner tips.

Attention is called to the fact that the burner tips are secured to thetop part of the burner 2 in a novel manner as follows:

A tongue-like flange 34 is formed integral therewith and is adapted tounderlap the top portion of the burner as shown in Fig. 1. I

noted that these flanges are made integral with the burner ti s andextend from the burner tips on a .di erent plane. They further serve tohold and maintain the burner tips in position. I The tongue-like flangesthat extend over the top surface ofthe top of the burner on each pair oftips extend inj'uxtapositionor toward each other, so that one screw 36.holds two (2) of the burner tips securely in place. Thepreferableconstruction of the burner and tips of the burner is of sheetmetal so as to afford a smooth and polished surface for enamelingpurposes, which smooth surface also obviates the friction of the gas andair in passing through the burner.

It will be noted, however, that the burner can be made of cast metal ifdesired without departing from the spirit or principle .of the inventionherein described.

Attention iscalled to the fact that this burner can be constructed uponan economical basis, asto labor as well as material.

It is not intended to confine the invention to the structure shown inthe drawing as many immaterial alterations or changes may be made, inthe structure without departing s from the spirit of theinvention.

I claim: I

1. A gas burner of the radiant type, comcomprising a section formed forthe passage of gas therethrough, means integral with the tip fordirectly receiving and sup orting the radiant, and upstanding lugs todirectly cooperate with the radiant at spaced points to maintain theradiant in position over the tip, the upper surface of the tip betweenthe lugs being rounded to permit the entrance of air beneath the edgesof the radiant when in position on such tip.

In testimony whereof I afiix my signature.
